If you can't believe how close former Real Housewives of Atlanta star Kim Zolciak is to giving birth to her twins, you're not the only one! Indeed, Kim herself is having trouble processing it all.

Kim and husband Kory Biermann are about to get a lot less sleep, as Kim is nine months pregnant with their twins. The couple already has two adorable boys, Kroy Jr. and Kash. Kim has daughters Brielle and Ariana from a previous relationship.

Kim took to Twitter to reflect on the fact that the upcoming big moment is finally starting to sink in. "It's crazy two think I'll be delivering 2 babies!" Kim tweets on November 20. "What a miracle!"

Kim is also very close with the doctor who will be delivering the babies. "We are so excited and so blessed to have the best OBGYN, he has delivered 3 of mine!" she adds.

When her doctor's daughter responded by saying, "This could be your last delivery with him," Kim wrote, "IT IS MY LAST. Thank God for your dad though, I know I drive him nuts!"

Kim has shared her affection for her doctor in the past. "I have the best/funniest OBGYN ever!!" she tweeted back in July.

Are you as excited as we are that Kim is about to add to her brood? And do you believe Kim that this will be her last pregnancy?
